(a(i))[2]
For the ball at point $P$, show that its vertical component of velocity is $14.2\,\text{m s}^{-1}$.
(a(ii))[2]
Find the vertical distance the ball has descended.
(a(iii))[2]
Find the horizontal distance $x$.
(b)[4]
The path of the ball in (a), with an initial horizontal speed of $8.2\,\text{m s}^{-1}$, is shown again in Fig. 2.2. On Fig. 2.2, sketch the revised path for a ball with initial horizontal speed (i) greater than $8.2\,\text{m s}^{-1}$ and negligible air resistance (label this path G), (ii) equal to $8.2\,\text{m s}^{-1}$ but with air resistance acting (label this path A).
(b(i))[2]
Greater than $8.2\,\text{m s}^{-1}$, with negligible air resistance, and label this path G.
(b(ii))[2]
Equal to $8.2\,\text{m s}^{-1}$, but with air resistance, and label this path A.
